Abstract

The power level of an RF signal is detected using a circuit having relatively low DC offset, high dynamic range, small frequency and temperature dependence and low flicker noise. According to one embodiment, the power detector circuit comprises a chain of amplifiers and a passive mixer. The chain of amplifiers converts the RF input signal to a supply-limited RF square wave signal. The passive mixer passively mixes the supply-limited RF square wave signal with the RF input signal and in response generates a rectified output signal that tracks the amplitude of the RF input signal.
